As a result of the growth of mobile devices such as PDA and cellular phone, a user can utilize various digital contents everywhere and anytime. However, mobile devices have the limited resources and interaction mechanisms. This paper introduces the schema for a user activity estimation and its application in order to overcome the poor user interface and limited resource problems. We are able to supplement lacking the user interface of mobile devices by using the user activity estimation proposed in this paper, and its application is a intelligent control interface for the display power on or off which can effectively utility the battery of the mobile device.

이 논문에서는 상황에 적합한 정보들을 선택하고 이를 해당되는 GUI (Graphic User Interface) 객체를 통해 사용자에게 제시하기 위한 규칙 기반의 지능적 사용적 인터페이스 구조를 제안하고, 이를 이용하여 실제로 군사 분야 정보 융합 시스템의 그래픽 사용자 인터페이스를 개발하였다. 군사분야와 같이 복잡하고 급변하는 상황에서는 상황에 따라 필요한 정보가 다를 뿐만 아니라, 불필요한 정보의 제시로 인해 오히려 사용자의 판단에 혼란을 초래할 수 있다. 이 논문에서는 이러한 점을 고려하여, 제시할 정보와 GUI 객체의 적절한 대응뿐만 아니라, 상황에 따라 사용자에게 필요한 정보를 해당분야의 전문가로부터 획득한 규칙에 의해 선택적으로 제시하도록 하기 위한 GUI 구조를 제안하였다. 개발한 GUI의 구조는 입력 해석, 제시할 정보의 선택, GUI 객체의 선택, GUI객체의 생성 및 속성 기정, GUI 객체의 배치 및 출력 단계들로 구성되며, 각각의 단계는 규칙에 의해 처리된다. 제안된 구조에 의해 공중 작전 수립을 위한 정보 융합 시스템의 사용자 인터페이스를 개발한 결과, 다양한 매체를 통해 많은 데이터가 들어오는 상황에서 필요한 정보만을 선택하여 적절히 제시해 줌으로써 사용자의 신속한 상황 판단과 결정 수립을 지원할 수 있었다.

This paper proposes an intelligent search modeling using avatar agent. This system consists of some modules such as agent interface, agent management, preprocessor, interface machine. Core-Symbol Database and Spell Checker are related to the preprocessor module and Interface Machine is connected with Best Aggregate Designer. Our avatar agent system does the indexing work that converts user's natural language type sentence to the proper words that is suitable for the specific branch information retrieval. Indexing is one of the preprocessing steps that make it possible to guarantee the specialty of user's input and increases the reliability of the result. It references a database that consists of synonym and specific branch dictionary. The resulting symbol after indexing is used for draft search by the internet search engine. The retrieval page position and link information are stored in the database. We experimented our system with the stock market keyword SAMSUNG_SDI, IBM, and SONY and compared the result with that of Altavista and Google search engine. It showed quite excellent results.

It become increasingly important to design user interface to carry low complexity. The cognitive limitations of users severely restrict utility of highly intelligent but complex modern systems. Since humans are known to use schemas to reduce cognitive complexity, imposing good consistency to an interface design that may help that user form useful schemas will provide powerful control over the complexity. This present a research effort to develop a quantitative method for evaluating interface complexity that the user would experience planning his or her course of action. Taking into account the user's potential schemas, a quantitative measure based on information theory was develped to assess the navigational complexity. This approach does not rely on the subjective judgment of the researcher as most schemes dealing with user schemas do. The proposed method may benefit the rapid prototyping approach to design a better user interface by allowing handy assessment of the design.

As the mobile computing technologies rapidly develops, the mobile phones are evolving into smart phones capable of higher performance. However, it is inevitable that the mobile phones have limited input/output functions in order to maintain the current portability. Because of the limited input and output, the mobile user interfaces currently adopt the inefficient structures based on sequential search and selection. In this paper, an intelligent and adaptive user interface techniques are proposed in order to surmount the current inefficiency of the static interface and to maximize the user convenience. The proposed techniques, based on the users' previous tasks, automatically generate an intelligent and adaptive user interface in order to make users efficiently utilize the mobile services.

Conventional home audio system (e.g. AV Receiver, CD Player etc) has a various functionality of audio play, channel mixing, but the remote controller of these audio players is too complex, difficult for user to manage them effectively. Users want to use these functionalities with more easy, comprehensible way. In this study, "intelligent real-sound presentation technology" that support high quality, realistic audio and the "design of complex information and controller of real sound using intelligent real sound play and control interface" will be introduced. So user can actively, realistically enjoy and play real sound based on user's preference, emotion and circumstance, instead of user's passive service.

The present Web surroundings is mostly composed of HTML(Hypertext Mark-up Language) and thereby users obtain web informations mainly in GUI(Graphical User Interface) environment by clicking mouse in order to keep up with hyperlinked informations. However it is very inconvenient to work in this environment comparing with easily accessed one in which human`s voice is utilized for obtaining informations. Using VoiceXML, resulted from XML, for supplying the information through telephone on the basis of the contemporary matured technology of voice recognition/synthesis to work out the inconvenience problem, this paper presents the research results about VoiceXML VUI(Voice User Interface) Browser designed and implemented for realizing its technology and also the VoiceXML Dialog designed for the purpose of the browser's efficient use.

국내 휴대 단말기기(Mobile Phone, PDA 및 DMB 폰 등)의 하드웨어적 컨버젼스 기술은 국제 경쟁력을 충분히 확보하고 세계 시장에서 선두 역할을 수행하고 있으나, 휴대 단말기기에 필수적으로 구성되어지는 UI(User Interface)는 상대적으로 낙후된 실정이다. 이에 따라 3차원 그래픽 UI의 구현과 휴대 단말기기의 이벤트에 반응하는 3차원 아바타 시스템 개발을 통해 경쟁력 있는 소프트웨어적 컨버젼스 시대의 대비는 필수적이며, 본 논문에서는 휴대 단말기에서 3차원 UI의 구현 뿐 아니라 쉽고 빠르게 UI를 구축 할 수 있는 Authoring Tool 개발의 시급성을 인식하여 연구를 진행하고 있다.
